MILK-"CAN.

SPECIFICATION forming part of Letters Patent No. 788,821, dated May 2, 1905.

Application filed January 20,1904. Serial No. 189.841.

To all whmn it may concern:

Be it known that I, JAcoB B. CoNovEn, a citizen of the United States, residing at Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Milk-Cans, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

My invention relates to milk-cans, and more particularly to the means for joining together the bodies and breasts thereof.

One of the objects of my invention is to effect a tight and rigid clamping together of such parts, so that the structure at and in proximity to the juncture of the body and breast will be capable of resisting all ordinary and extraordinary strains and concus sions and will maintain its integrity and shape notwithstanding the rough usage to which milk-cans are frequently subjected.

Other objects of my invention are to effect economies in the cost of manufacture of milkcans and to generally simplify and improve parts together. Fig. l is a similar view of a modified construction. Fig. 5 is a similar view of another modified construction, showing at the upper part of the ring the initial position and at the lower part of the ring the final position of the clamping-lips on the stifi'ening-ring. Fig. 6 is a similar view of another modified construction, showing at the lower part of the ring the initial position and at the upper part of the ring the final position of the clamping-lips of the stiffeningring.

The 1nilk-can,partly shown in the drawings, is oi ordinary construction except at the juncture of the body a and breast I). At this part of the can a ring is provided, which takes the place of the ordinary reinforcinghoop and performs the usual function of such hoop in imparting stillness to the can and also performs the function of locking the body and the breast together. The sti'fl em ing-ring-c is separately shown in Fig. 2 in its condition before attachment to the adjacent parts of the can. lit has an upper groove (Z,

0 I will now describe the constructions em- In Figs. 1 and 3 the parts are shown in at 0 bodying my invention illustrated in the actached condition.

Figure 1 is an elevation, partly in section, lower portion n of the breast immediately of the upper part of a milk-can. Fig. 2 is an above the flange extends outward from the enlarged section of the stiffening eonnectingring before attachment to the body and breast. Fig. 3 is an enlarged section of this ring and adjacent parts of the body and contour of the breast, having an outward and downward flare, and the outer upper portion of thelip m is correspondingly shaped, so as to fit tightly against the flaring portion a of the breast. The contour of the breast 50 breast after attachment and clamping of the merges into this flaring lower portion a without abrupt turns or corners, and the inner juncture of the upper end of the lip m of the stiffening-ring and of the breast presents no abrupt corner or pocket. In Figs. 1 and 3 an inwardly-extending flange g at the upper end of the body is shown as clamped within the lower groove f, and the lower clampinglip 0 tapers downward and inward, and the part p of the body immediately below the flange is flaring to fit tightly the tapering lower part of the stiffening-ring, and this flaring portion of the body merges into the cylindrical part thereof without abrupt turns or corners. The angular bends of the flanges of the breast and body, the tight gripping of these flanges in their grooves, and the inner supports afforded by the lips m and 0, respectively, eflectively prevent any forcing inward of the breast or body in proximity to the stiffening-ring, and the stiffening-ring effectively joins together the body and breast. To assure continuity of the inner surface of the can, the inner junctures of the stiffeningring and breast and body may be united by tin, solder, or other suitable cementing ma terial, as indicated at It and 'i, respectively. Only light soldering would be required, and the joint could be effectively closed by tinning the parts after assembling.

In the modified construction shownin Fig. 4 a groove cl is provided only for the breast b, and the breast extends outward and has a flange e, which enters this groove. The clamping-lip m of the stiffening-ring above the groove is of rectangular crosssection, and the outwardly-extending lower part n of the breast immediately above the flange follows closely the contour of the lip m and then merges into the ordinary breast shape. The stiffening-ring is here a hoop or band fitted over the upper portion of the body a and having a bumper 1 formed thereon and tapering inward toward its lower end to save weight and avoid an abrupt outer corner. The single inner juncture may be closed by tin or solder or other cementing material, as indicated at h.

In the modified construction shown in Fig. 5 the breast 6 extends outward and has a flange e, which is turned downward into a corresponding upper groove 6V, and the stiffening-ring c has an upwardly-extending clamping-lip j, which is turned inward after the breast-flange has been inserted in the groove, thereby tightly locking the breastflange, and the body (1 extends outward at its upper portion and has a flange 9 turned upward into a corresponding lower groovef and locked by a clamping-lip k, which originally extends downward and which is turned inward over the flange.

6 the breast extends outward at its lower portion and has a flange 6 turned upward and entering an upper pocket d in the stiffening-ring 0 The stiffening-flange c has a clamping-lip j, which originally extends inward and which it turned down upon the breast-flange to tightly clamp it. The body a extends outward at its upper part and has a flange g entering a lower pocketf in the stiflening-ring and is locked by a clampinglip similar to the upper clamping-lip. The initial position is shown as to the lower clamping-lip k and the final position as to the upper clamping-lip 7'. In other respects the construction is as heretofore described, a bumper r being provided on the stiffeningring It is obvious that various other modifications of construction may be made within the spirit and scope of my invention.

hat I claim, and desire to secure by Letters Patent, is

1. A milk-can having a stiffening-ring clamping the edge of a part of the can, such stiffening-ring having an annular groove receiving such edge and a clamping-lip forming one of the walls of such annular groove and exteriorly covered by such part.

2. A milk-can having a stiffening-ring clamping the edge of a part of the can, such part of the can having an end flange and a portion adjacent thereto extending outward from the contour of such part of the can, the flange extending at an angle to such outwardly-extending portion, and the stiffeningring having a groove receiving such flange and a clamping-lip forming one of the walls of such groove and clamping such flange.

3. A milk-can having a stiffening-ring clamping the edge of a part of the can, such stifl'ening-ring having a groove receiving an inwardly-extending flange of such part and having a clamping-lip tapering downward to a smooth joint with such part in the interior of the can.

In testimony whereof I have aflixed my signature in presence of two witnesses.
